Abstract: A ramp door suited to pivot about an axis that extends substantially horizontally along the bottom of a cargo compartment opening has features of lightweight construction that may be used separately or in combination with features of a frame assembly having an upright configured to extend substantially vertically along one side of the opening to provide an interior space that may be used to house components of a ramp door lift assist system and/or components of a ramp door latching system. In some embodiments, the extent to which a lift assist cable is exposed when the ramp door is open is minimized by connecting the cable to the ramp door, and by guiding the cable into the interior space of the upright, at locations relatively near to the pivot axis.

Abstract: A magnetic separator system comprises a feed chute having an adjustable feed chute floor portion for controlling the release of discharge slurry from the feed chute onto a rotating magnetic drum separator. Adjusting the adjustable chute floor portion controls where discharge slurry released from the feed chute contacts the outer surface of the drum, allowing the contact point to be maintained for optimal separation simply through such adjustments. Precise control over flow of discharge slurry onto the drum notwithstanding variations in flow of discharge slurry permits the system to use an open construction, which is more compact and which reduces wear and abrasion and makes the system more accessible for repair. The field of attraction from magnets within the drum extends not only around the circumference of the drum, but also into the feed chute over the adjustable feed chute floor portion.
